Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed January 8, 190.81 Serial No. 409,872.

To all whom it may concern:

Be it known that I, Gnonons LAKHovsKY, resident of 5 Avenue du Bois deBoulogne, in the city of Paris, Republic of France, have inventedImprovements in or Connected with Means for Fastening in PositionRailway-Spikes or the Like, of which the following is a full, clear, andexact description.

The present invention relates to a metallic fitting constituting a kindof divided nut adapted to fix itself in railway sleepers to receive theordinary spikes employed either for retention of broad footed rails orfor fixin in position the chairs which receive doub e headed rails.

This fitting can be applied either to new i or to old sleepers; in theformer case it permits soft wood to be utilized as sleepers for railwaysby lining the walls of the spike holes with metal; 11'! the latter casethe same fitting may be fixed in the spike holes and thus permit oldsleepers of hard wood to be utilized without its being necessary to borenew holes the old holes simply being enlarged to the diameter of thefitting. F urthermore, the spike, fixed in the sleepers by the aid ofthis fitting possesses much more durability and resistance to drawingout than those fixed directly into the wood. The fibers of the wood arecompressed and hardened owing to the outline or profile of the fittingat first at the time of putting in place the shells in the sleeper andafterwards when the spike is screwed into the same in such manner thatthe nut so constituted possesses a large amount of resistance to drawingout.

This fitting, which forms a metallic nut, also allows the spike to bewithdrawn when desired without in any way disturbing the solidity of thestructure inasmuch as the screwing and unscrewing of the spike cannotinjure the thread of the screw or of the nut. Furthermore, the spike canbe tightened up many times if in use the arts become loose owing to theplay of the s eepers.

In the accompanying drawings: Figure 1 is an elevation of a duplexfitting constructed according to the resent invention. Fig. 2 is a lanthereo Fi 3 is an inside elevation 0 one of the two shells constitutingthe fitting. Fig. 4 represents the ap lication of this invention to thefixing of a road footed rail upon a sleeper. Fig. 5 shows theapplication of the invention to the fixing of a chair for a doubleheaded rail. Fig. 6 is an elevation of an instrument for placing thefitting in position.

Referring to the drawings the fitting is formed by two metallic shells ahalf cylindrical in section and independent of one another. These shellsare interiorly formed with a female screw thread inclosing a conicalcavity 5 to receive the stem of the ordinary spike 0 employed onrailways for the fixing of the rails. Upon their exterior the shells aare formed with a number of steps or teeth d arranged circumferentiallyand also with longitudinal beads or projections 6 formed preferablyalong the edges of the shells. The teeth d are adapted to enter andcompress the fibers of the wood in such manner as to prevent the pullinor working out of the fitting a while the ribs e prevent the shells aturning in the hole f in the sleepers when the spike is screwedthereinto. After having bored or rebored the holes in the sleeper to asuitable diameter the fitting is placed in position by forcing into thehole the two shells a by means of an appropriate instrument such as that9 (Fig. 6) which is driven by the aid of a hammer until the upper edgeof the fitting has descended slightly beneath the surface of thesleeper. The s ike c is then screwed into the fitting until its headbears upon the foot h of the rail or upon its chair i. During thisoperation, the spike c, which is entering the fittin a, owing to theconical screw thread Z) thereo causes the spreading apart of the twoshells which has the effect of compressing the fibers of the wood andcausing the steps or teeth 05 to enter the wood thus securely fixing theparts in position.

The operation of screwing up the spike can be performed without fear ofturning the shells a which form the nut owing to the said longitudinalribs or beads e.

In the fitting adapted to broad footed rails as shown in Fig. 4, one ofthe shells is formed shorter than the other so as to avoid the foot ofthe rail coming into contact with said shell when screwing or tighteningup the spike.

The fitting adapted to rail chairs 2' is, as shown in Fig. 5, preferablyprovided with a washer of hard wood 7' interposed between the undersideof the chair and the upper edge of the fitting.

The washer g has for its object to fill in the gap left in the spikehole in the sleeper to permit the subsequent ti htening of the chair byscrewing u the spi e 0.

- The forms, detai s, accessories, materials and dimensions of thisfitting may be varied without departing from the principle of theinvention.

Claims:

1. A socket having an interiorly screw threaded conical cavity, saidsocket being divided longitudinally into sections.

2. A socket having an interiorly screw threaded conical cavity, saidsocket being divided longitudinally into sections, the edges of thesections being provided with laterally projecting ribs for the purposeset forth.

3. A socket having an interiorly screw threaded conical cavit saidsocket being divided longitudinally into sections, the outer face of thesocket being provided with u Wardly facing teeth for the purpose setfortii.

4. A. socket havin an interiorly screw threaded conical cavity, saidsocket being divided longitudinally into sections, and a washer arrangedbetween the sections and the rail chair for the purpose set forth.
